The Republic of Ireland is divided into 30 administrative regions, mostly tied to the 26 constituent counties (county Tipperary is divided in two and county Dublin in four).
Most visits to Ireland are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
Ireland has a long and honourable tradition in education. As a result of a sustained investment in this area Ireland now has one of the highest educational participation rates in the world - 81% of Irish students complete second-level and approx 60% go on to higher education. This dynamic, educated population has made its mark at home and abroad with international companies looking to Ireland again and again when hiring graduates for top class positions.
